EasyMining patented process Ash2®Phos enables extraction of clean commercial phosphorus products from ash of incinerated sewage sludge. Thereby the need for virgin phosphorus resources can be decreased, and a circular flow of phosphorus established, an element of high importance to the EU and of high risk associated with their supply. In addition to phosphorus the Ash2®Phos process recovers precipitation chemicals and remove heavy metals.

Phosphorus is an essential element for life and a key nutrient for agriculture. Via the food cycle, phosphorus ends up in sewage sludge.
